Secondly, I need to determine the volume of a puddle, using a robot able just to move and detect puddles.
It means that it needs to demonstrate its purpose in a controlled environment.
The purpose is to find puddles (if any) on the floor. However, it will have it own pre-established course. I need it to be able to detect a puddle if its about 1m away from the front or the sides, while maintaining that course.
I am very aware of the risks of acids, bases, whatever concentration or pH they have.
The robot will neutralise them, thats not the main concern.
